You are right about people going for some profession because of the pay or because that is the only choice available at the time. I have seen this among military and paramilitary organizations. Unemployment rather than passion pushed some people into it and it manifests in the actions.
Another thing is that one that doesn't go for his passion tends to be unhappy at any slightest disappointment in what drew him to the job. It's awesome to like what you do. You work without necessarily being supervised or forced to.
Thank you for your prayers @abdul-qudus. Thank you for your prayers.
